1808438357Is a seed alive?Yes0
1808438358What does a living thing have to have to be declared living?1. Capable of Reproduction 2. A Metabolism 3. Be able to Grow/Develop 4. Genetic Information 5. Cellular Structure 6. Capable of Responding to Stimuli 7. Capable of death 8. Homeostasis1
1808438359What is a metabolism?Being able to extract the necessary nutrients from food, in order to survive2
1808438360What is homeostasis?Being able to maintain stable conditions inside the organism3
1808438361What evidence shows that seeds reproduce?They carry an embryo which can be germinated and eventually develop into a plant4
1808438362What evidence shows a seed metabolizes?A seed has an embryo and in order for the embryo to stay alive it must gather the nutrients it needs, so there must be a metabolism5
1808438363What evidence shows that a seed can grow/develop?When germinated, the embryo can grow, and a plant forms6
1808438364What evidence shows a seed has genetic information?If you were to crush a seed and then spool the remains, you would be able to see the DNA within a microscope7
1808438365What evidence shows a seed has cellular structure?You could view a seed under a microscope and see the cells8
1808438366What evidence shows a seed is capable of responding to stimuli?When you put a seed into water, it responds by eventually growing/developing. Also, if you heat a seed, it speeds up the process of growth9
1808438367What evidence shows a seed can die?You can conduct an experiment where you heat 10 seeds and leave the other seeds normal. You put all 20 seeds into water and wait until they grow. If 7/10 seeds of the heated seeds don't grow while all the other 10 normal seeds do, then that means that they can die10
1808438368What evidence shows a seed has homeostasis?It has to have stable ph and acidic levels because it needs to maintain a certain body temperature, otherwise it would die11
1808438432What is a Bunsen Burner?A piece of equipment that spews out gas, allowing you to produce an open flame with either a striker or a lighter12

1808438394What famous book did Darwin ultimately publish?Origin of Species by Means of Natural Selection57
1808438395When was Darwin born?February 12th, 180958
1808438396Where was Darwin born?Shewsbury, England59
1808438397Who did Darwin marry?Emma Wedgehood60
1808438398What was weird about this marriage?She was his first cousin, and his dad had also married a member from the Wedgehood family61
1808438399How did Darwin die?Heart failure, probably from a disease given to him during his visit to South America62
1808438400What was the controversy between natural selection and creationism?Creationist believed God had created everything on Earth and that everything had stayed the same or a new species was born opposed to natural selection where species are thought to have evolved63
1808438401How did this affect Darwin?He was a very religious person, and felt that publishing his works on natural selection worked against God64
1808438402Can individuals evolve?NO, individuals receive variations, but only species can evolve65
1808438403What were Darwin's five conclusions?1. Natural variation happens among individuals of a population 2. The variation is heritable 3. More are born than can survive 4. Only the fittest individuals survive 5. The ones with the favorable traits (adaptations) have greater reproductive success and more representatives in future generations66
1808438404How does natural selection work?Over years as factors in the environment or habitat change, certain traits either become adapted or are lost to a species67
1808438405What is a good example of natural selection?The finches in the Galapagos Islands: Finches have adopted different forms of beaks in order to eat the food they need68
1808438406What did Thomas Malthus find?The food/resources grew linearly or arithmetically while population grew exponentially69
1808438407How did Malthus influence Darwin?If Malthus's theory was correct, humans would then have to adapt to the new amount of resources and try to survive, so it helped him discover survival of the fittest70
1808438408What did Jean Baptiste Lamarck find?He said that individuals with certain traits can survive, while other individuals lacking these traits can't71
1808438409How did Lamarck influence Darwin?It made Darwin think about how the environment affected the species, and that the individuals with favorable traits reproduce stronger offspring and survive longer72
1808438410What did Charles Lyell and James Hutton find?Theory of Uniformitarianism- geological forces have stayed the same throughout the history of the Earth proving the Earth is very old73
1808438411How did Lyell and Hutton influence Darwin?Darwin believed evolution took too long and the Earth was relatively young, so evolution couldn't have happened. Now that he knew Earth was actually really old, he began to think evolution was possible.74
1808438412What did Alfred Russel Wallace find?He discovered natural selection in the Malayan Archipelago75
1808438413How did Wallace influence Darwin?It affirmed Darwin that natural selection was real because another scientist had discovered the same concept on his own76
1808438414What was a pushing factor for Darwin to release his findings?The letter from Alfred Wallace77
1808438415How do the finches explain Darwin's Theory of Evolution?1. Certain finches received variations in their beaks while others didn't 2. Once a few of the beaks were changed, the genes were passed down to their offspring 3. Many finches were born, but many ended up dying 4. Only the finches that received the variations were able to survive and get the food they needed 5. Finches that received beaks that allowed them to extract food allowed them to survive and reproduce stronger offspring78
1808438416What was important about Peter and Rosemary Grant?They were able to notice that the beak depth evolved once drought arrived in the Galapagos Islands, describing micro-evolution.79
1808438417What is allopatric speciation?When a geographical barrier forces a species to adapt into 2 new species80
1808438418What is sympatric speciation?When a species separates from each other within the same geographical area and adapts into 2 new species81
1808438419What is a variation?a natural changes in genes (brown hair, height, skin color, etc.)82
1808438420What is natural selection?When species either adapt or "discontinue" certain traits because of changes in the environment83
1808438421What were the different finches that received variations in their bills?1. Seed Eaters 2. Fruit Eaters 3. Tool users 4. "Vampire" beaks84
1808438422What is evolution?The gradual increase in variation of traits through generations85
1808438423What is adaptive radiation?When a species is forced to quickly adapt into 2 or more new species because of a sudden change in the environment86
1808438424What are the prime examples of adaptive radiation?1. Finches in the Galapagos Islands 2. Drosophila and Scaptomyza (fruit flies) in Hawaii 3. Cichlids (fish) in Lake Victoria87
1808438425What happened to the Cichlids in Lake Victoria?Due to a loss in water depth, the lake split into multiple ponds making the fish adapt to their new and smaller environments88
1808438426What is the difference between spore plants and seed plants?Seed plants are ubiquitous89
1808438427How did the seed evolve, allowing it to remain dormant?1. Developed a protective coat allowing the embryo to withstand extreme temperatures, the PH of animal guts, and droughts 2. Also Developed nutritive tissue which gives nutrients to the embryo until the seed finds the right temperature and environment90
1808438429What kind of seeds do angiosperms produce?Covered seeds91
1808438430What kind of seeds do gymnosperms produce?"Naked" seeds92
1813152548Review your period's lab...93
1813152549Review safety rules pertaining to your period's lab...94
1828176043How do you find the density of the colonies on a stock plate?The amount of colonies divided by the area95
